1// Source: https://www.w3.org/TR/wai-aria-1.1/#roles2/* easiest way to see allowed roles is to filter out the global ones3   from the list of inherited states and properties. The dpub spec4   does not have the global list so you'll need to copy over from5   the wai-aria one:6  const globalAttrs = Array.from(7    document.querySelectorAll('#global_states li')8  ).map(li => li.textContent.replace(/\s*\(.*\)/, ''));9  const globalRoleAttrs = Array.from(10    document.querySelectorAll('.role-inherited li')11  ).filter(li => globalAttrs.includes(li.textContent.replace(/\s*\(.*\)/, '')))12  globalRoleAttrs.forEach(li => li.style.display = 'none');13*/14const ariaRoles = {15	alert: {16		type: 'widget',17		allowedAttrs:
